IMPROVEMENT IN WATER-WHEELS.

Specification forming part of Letters Patent No. 153.246, dated July 21, 1874; application filed J une 27, 1874.

To all whom it may concern;

Be it known that I, JEREMIAH J. DonsoN, of Greensborough,in the county of Guilford and State of North Carolina, have invented a new and Improved Water-Wheel, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a vertical central section, on the line 0 c, Fig. 2, of my improved water-wheel; and Fig. 2 a top view of the same, with parts of cap-piece and cover cut oil' to show construction of buckets.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved waterwheel which combines with simplicity of construction a full utilization of the pressure of the water-head; and it consists of a wheel made with buckets whose width increases from the central conical entrance part toward their middle sections, and diminishes toward the issuing-ports at the circumference. The water enters through diametrical chutes at the top, andan enlarged water-space of the cap-piece, to the conical center and the buckets.

In the drawing, A represents the waterwheel, constructed of wood, iron, or other suitable material, and of a size corresponding to the head of water. The shaft to is centrally keyed to the wheelA, which has a conical center part, I), the bucketdividing walls B being tapering thereto. A suitable number of buckets, 0, according to the size of the wheel, are produced by dividing the wheel by concentric circles, at equal distances, into three parts, subdividing then the circumference into as many parts as buckets are required, and drawing, by a radius equal to two-thirds part of the wheel-radius, circles from the points at the circumference to a circle about half-way between the inner circles, with the center of these bucket-lines on the inner circle. The opposite side of the buckets is formed by a circle whose width from the bucket-line increases gradually from the intermediate circle to the circumference, so as to produce thereby buckets with greater width in the center, and decreasing width toward the issuing-ports. A cap, D, equal to the outer third of wheel A, is placed on the wheel, the central part b tapering upward, to give a larger water space. The cap and wheel are then applied to a covering, E, with diametrical sector-shaped waterchutes F, which extend from the interior to the second circle of the wheel, and are made large enough to let in double the amount of water as the issuing-ports will let out. A considerable pressure of the water in the buckets is thereby produced, and the wheel rotated with increased utilization of the power of the waterhead.

The wheel is simple, cheap, and durable and may be supported in a suitable frame.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A water-wheel having central conical part, with buckets extending therefrom which increase in width toward the central part thereof, and taper toward the narrower issuin g-parts, constructed substantially as and for g the purpose set forth.

2. The combination of the water-wheel A, with the cap-piece D, and cover E, with chutes F, forming enlarged water-space above conical part of wheel, for acting with increased pressure on buckets, substantially as specified.
